How do I move the position where the nozzle primes before pr

I have a Flashforge Creator Pro. When I use S3D, the nozzle moves to the front right corner and extrudes a few mm of filament before it prints. My issue is, that the nozzle is sitting on the bed when it does that so the feed clicks. What I would like to do is have the nozzle perform this task a few more mm to the right so it is off the bed when it extrudes the filament. How (exactly) do I configure S3D to move the nozzle a little to the right when performing this task.

Thank you
Bill

This is controlled by gcode lines in the starting script.

See this thread for starters: viewtopic.php?f=8&t=4889&p=21122&hilit= ... zle#p21122

If you can't work out what to change, post your starting script.....

Are you using the FF Creator Pro 2016 ? If so, try this out -> viewtopic.php?f=8&t=6183&p=26817#p26817
They prime by drawing a complete line across the bed

OK..I tried Kabali's suggestion re-saved my file to the SD card but the nozzle did the same thing.
Yes, I have the FFCP 2016.
Doug, there also is no line of code saying (purge anything).
Here is my Gcode:

; **** Replicator 1 dual start.gcode ****
M73 P0 ; enable build progress
G162 X Y F3000 ; home XY maximum
G161 Z F1200 ; home Z minimum
G92 Z-5 ; set Z to -5
G1 Z0 ; move Z to 0
G161 Z F100 ; home Z slowly
M132 X Y Z A B ; recall home offsets
M135 T0 ; load right extruder offsets
G1 X150 Y-70 Z30 F9000 ; move to wait position right hand side of the table
